Anderson, 26, went 1-4 with a 6.04 ERA last season in 16 games (5 starts) with the Athletics. He missed 104 games with an ankle sprain that kept him sidelined from April 30 to August 28. In his five starts in 2013, Anderson went 1-4 with a 7.23 ERA. In 3 rehab starts, Anderson went 0-2 with a 12.54 ERA. Anderson has been injury-plagued over his career, missing 408 games since the 2009 season. He had Tommy John surgery in 2011, and missed most of 2012 from the injury.
Over his career, Anderson is 26-29 with a 3.81 ERA and a 1.28 WHIP. In his only season over 30 starts (2009), Anderson went 11-11 with a 4.06 ERA and a 1.28 WHIP. He his a solid, reliable pitcher when healthy. Health, however, is a big issue for Anderson. If the Rockies can get a healthy Anderson, they'll have won this trade. If not, they will have lost it. He is still young and hopefully will be able to put his injuries behind him.
The Athletics will be receiving pitchers Drew Pomeranz and Chris Jensen. Promeranz has a career 5.20 ERA and a 1.54 WHIP in 34 appearances (30 starts) since the 2011 season. They have all come with the Rockies. Jensen has a career 4.22 ERA in 61 minor league starts (334.2 IP). In class-A advanced last season, Jensen went 5-8 with a 4.55 ERA in 28 starts.
